Abstract

A new azomethine compound 4-methyl-N-[2-pentafluorophenyliminomethyl)phenyl]methylbenzenesulfamide and a Cu(II) complex based on it are obtained and characterized by ¹H NMR, IR spectroscopy and the elemental analysis. Crystal structures of azomethine and its complex are analyzed by single crystal X-ray diffraction (XRD). From the single crystal XRD data it is found that the Cu(II) complex crystallizes in the triclinic space group \(P\bar{1}\). The unit cell contains two crystallographically independent mononuclear molecules with similar geometries. In the complex, copper ions have a distorted tetrahedral environment of four nitrogen atoms, which is formed by two bidentate coordinated azomethine ligands. From magnetic measurements it is found that the Cu(II) complex is paramagnetic.

摘要

获得了一种新的偶氮甲碱化合物4-甲基-N-[2-五氟苯基亚氨基甲基)苯基]甲基苯磺酰胺及其Cu(II)配合物，并通过¹ H NMR、IR光谱和元素分析对其进行了表征。通过单晶 X 射线衍射 (XRD) 分析了偶氮甲碱及其配合物的晶体结构。从单晶 XRD 数据发现 Cu(II) 配合物在三斜空间群\(P\bar{1}\)中结晶。晶胞包含两个具有相似几何形状的晶体学独立的单核分子。在配合物中，铜离子具有四个氮原子的扭曲四面体环境，该四面体环境由两个二齿配位偶氮甲碱配体形成。通过磁性测量发现 Cu(II) 配合物具有顺磁性。
